Hello, I'm trying to calibrate a material I tested in real life for Abaqus, but the program keeps displaying the error whatever I do. I even converted the stress-strsin curve from engineering to true stress/strain but it didn't solve the problem. Please help!
If this is related to the plastic hardening table, the independent variable referred to is the plastic strain. The data lines have stress in the first data field and strain in the second data field. The plastic strains in the second field must be in non-decreasing order; i.e., the plastic strain value on each of the second and subsequent lines must be greater than or equal to the corresponding value on the preceding line.
Maciej Gierulski,
also, you can use this Abaqus plugin for further investigation

Good luck
